Procurement Notes
Verify the manufacturer part number SSR21NV-M25103 against official KEMET documentation to ensure authenticity. Confirm that the required specifications, including 10.3 mH inductance and 2.5 A current rating, match the design requirements. Check for RoHS compliance status as indicated in the datasheet. Ensure the through-hole package dimensions fit the intended PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring common mode chokes with a 10.3 mH inductance and 2.5 A current handling capability. The 250 VAC rating makes it suitable for standard AC line applications. Consider the 120 mOhm DCR for efficiency calculations. The through-hole format is appropriate for prototyping or high-reliability assemblies where surface mount options are not preferred. Verify thermal performance within the -25°C to +120°C operating range.
Part Context
This component belongs to the KEMET SSR21NV-M series of common mode filters. These components are engineered for AC line filtering tasks. The series offers various inductance and current ratings to suit different power levels. The SSR21NV-M25103 specifically targets applications needing moderate inductance with higher current capacity compared to lower-rated variants in the same family.
Replacement Considerations
Check for direct substitutes within the SSR21NV-M series with compatible inductance and current ratings. Verify pin compatibility and physical dimensions if replacing on existing PCBs. Ensure the replacement part meets the same voltage and temperature specifications.
